Internet video rental company Netflix Corp.'s legal claims against rival Blockbuster Inc. are based on unenforceable patents, Blockbuster said in a counterclaim filed Tuesday.
In a bid to shut down Blockbuster's online service, Netflix had sued Blockbuster, the leading movie and game rental company. But Dallas-based Blockbuster said Tuesday that the lawsuit was based on patents Netflix obtained deceptively, in a bid to monopolize online rentals.
In an April lawsuit, Netflix accused Blockbuster of starting its online service in 2004 despite knowing that the service infringed a Netflix patent.
"There is nothing original about renting movies or subscription rental programs," Blockbuster lawyer Marshall Grossman said, noting both were widely practiced long before any such invention by Netflix.
